We're dividing 45216169 by 549 
We're looking to find how many times 549 goes into 45216169.

On to step 1:
The number 549 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 549

Advancing to step 2:
549 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 549

Let's proceed to step 3:
549 can be fit into 452 0 times, resulting in a remainder of 452.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 452 leaves us with 452.
Include the next digit (1) from the dividend after 452, then repeat: 4521 / 549

Advancing to step 4:
If we divide 4521 by 549, we get 8 and a remainder of 129.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 4392 from 4521 and we're left with 129.
Take the next digit (6) from the dividend and append it to 129, then repeat: 1296 / 549

Let's proceed to step 5:
When dividing 1296 by 549, we get 2 with a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Deduct 1098 from 1296 and we're left with 198.
Grab the next digit (1) from the dividend, add it to 198, then carry on: 1981 / 549

Step 6:
The number 549 fits into 1981 3 times, leaving a remainder of 334.
The next digit of our result is 3. 
Result so far: 823.0
The remainder is 334 after subtracting 1647 from 1981.
Take the next digit (6) from the dividend and append it to 334, then repeat: 3346 / 549

Let's proceed to step 7:
549 can be fit into 3346 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 8236.0
Subtract 3294 from 3346 to get 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 549

Advancing to step 8:
The number 549 fits into 529 0 times, leaving a remainder of 529.
The next digit of our result is 0. 
Result so far: 82360.0
Subtract 0 from 529 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 9:
549 can be fit into 5290 9 times, resulting in a remainder of 349.
Write down 9 as next digit of the result. 
Result so far: 82360.9
If we subtract 4941 from 5290, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Let's proceed to step 10:
549 can be fit into 3490 6 times, resulting in a remainder of 196.
The next digit of our result is 6. 
Result so far: 82360.96
Deduct 3294 from 3490 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
The number 549 fits into 1960 3 times, leaving a remainder of 313.
Write down 3 as next digit of the result. 
Result so far: 82360.963
Deduct 1647 from 1960 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 12:
When dividing 3130 by 549, we get 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 82360.9635
Deduct 2745 from 3130 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 13:
549 goes into 3850 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 82360.96357
Subtracting 3843 from 3850 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
When dividing 70 by 549, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 82360.96357
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
When dividing 700 by 549, we get 1 with a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 82360.9635701
Subtract 549 from 700 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 16:
1510 divided by 549 is 2 with a remainder of 412.
The number 2 becomes the next digit in our result. 
Result so far: 82360.96357012
If we take 1098 away from 1510, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The final result is 82360.96357012 with a remainder of 4.12e-07.
